FLOATING TYPE TIDE EMBANKMENT
PROBLEM TO BE SOLVED: To provide a floating type tide embankment which less affects lifting of a tide preventive structure even when a ground is deformed, prevents a floating trouble of the tide preventive structure by a bottom sediment, can smoothly float the tide preventive structure, and can prevent a flow of water toward a dike through a water flow passage in a caisson.SOLUTION: A floating type tide embankment divides the inside of a caisson 12 embedded in a bottom ground into a structure lift chamber 13 in a central part and inflow chambers 15A and 15B by lifting on both side parts by partition walls 16A and 16B, and stores a tide preventive structure 19 having a floating port 18 in the structure lift chamber 13 in a liftable manner. The tide preventive structure 19 lifts between a storage position of the structure lift chamber 13 and a floating position where the upper end face is arranged on a water surface by a lifting device. On an upper face opening of each of the inflow chambers 15A and 15B by lifting, a lid body 50 that is opened only while the tide preventive structure floats by lid opening/closing means is provided.SELECTED DRAWING: Figure 2
【課題】地盤が変形しても防潮構造物の昇降の影響が少なく、底沈降物による防潮構造物の浮上障害を防ぎ、防潮構造物を円滑に浮上でき、ケーソン内の流水路を通して堤内へ向かう水の流れを阻止できる浮上式防潮堤を提供する。【解決手段】底地盤に埋設したケーソン１２内を仕切壁１６Ａ、１６Ｂにより中央部の構造物昇降室１３と、両側部の浮上時流入室１５Ａ、１５Ｂとに分割し、構造物昇降室１３に、浮上函１８を有した防潮構造物１９を昇降自在に収納する。防潮構造物１９は、昇降装置によって構造物昇降室１３の収納位置と、上端面が水面上に配される浮上位置との間で昇降する。各浮上時流入室１５Ａ、１５Ｂの上面開口部には、蓋体開閉手段によって防潮構造物が浮上する間のみ開く蓋体５０を設ける。【選択図】図２
